A couple of the Intl tests made calls to getDefaultTimeZone(), which
doesn't exist in V8; however, these were not core to the test. Rather
than marking the whole test as failing, just comment out that
unimportant part of the test.

Before this change traps always returned a 32 bit word in tests. With this
change traps return either a 32 bit word or a64 bit word, depending on the size
of the actual return value of the test.
Additionally this CL implements the wasm instructions I64SCONVERTF32,
I64UCONVERTF32, I64SCONVERTF64, and I64UCONVERTF64.

TryTruncateFloat32ToUint64 converts a float32 to a uint64. Additionally it
provides an optional second return value which indicates whether the conversion
succeeded (i.e. float32 value was within uint64 range) or not.
I implemented the new operator on x64, arm64, and mips64. @v8-ppc-ports, can you
please take care of the ppc64 implementation of the second output?
Additionally I fixed a bug on x64 and mips64 in the implementation of
TryTruncateFloat64ToUint64. Cases where the input value was between -1 and 0
were handled incorrectly.

As discussed in person, this adds the code from v8-native-prototype into
V8 proper, guarded by GYP flags that do not build the code by default.
Passing wasm=on to 'make' or setting v8_wasm as a GYP flag activates
building of this code.
An additional header file is added to and exported from the compiler
directory, src/compiler/wasm-compiler.h. This exposes a limited interface
with opaque Node and Graph types to the decoder to build TF graphs, as
well as functions to compile WASM graphs.
The mjsunit tests added are blacklisted because they fail without the
WASM object exposed to JS, which is also disabled by the build config
option.
This corresponds closely to 5981e06ebc, with some formatting fixes and moving some files into src/compiler.

This patch removes Promise functions and methods which are absent
from the ES2015 specification when the --es-staging flag is on.
The patch is being relanded after being reverted due to an
unrelated bug. This version is slightly different as promise_chain
is installed on the context regardless of the flag value, so that
the Promise::Chain API continues to work until it is deprecated.

There's at least one case of a time zone alias: Asia/Kathmandu aliases
Asia/Katmandu. ICU seems to normalize to the (deprecated) latter choice.
V8 internationalization choked on this change; this patch interprets
ICU's output more precisely and allows it.

Without this fix, AssignmentExpressions that happen to be arrow functions
would lead to unbalanced Enter/Leave calls on the fni_, causing thrashing
while trying to infer function names. Symptoms include slow parsing
or OOM (when we create too many AstConsStrings).
To try to keep this from happening in the future, added an RAII helper
class to handle Entering/Leaving FNI state.
The included regression test crashes on my workstation without the patch.
Note that it's too slow in debug mode (as well as under TurboFan),
so I've skipped it there.

Function subclasses did not have function properties installed (name, prototype, etc.).
Now when an instance of a Function subclass is created it gets initial map that corresponds
to the language mode of the function body. The language mode dependent maps are cached as
special transitions on initial map of the subclass constructor.

When the reviver returns undefined, the property in question must be deleted
even for arrays. So far this only happened for non-array objects.
Also change the property enumeration to be spec-conformant, which is observable when the reviver modifies its "this" object directly. There are a few further issues that need to be addressed in a separate CL.

MachineType is now a class with two enum fields:
- MachineRepresentation
- MachineSemantic
Both enums are usable on their own, and this change switches some places from using MachineType to use just MachineRepresentation. Most notably:
- register allocator now uses just the representation.
- Phi and Select nodes only refer to representations.

This operator now provides a second output which indicates whether the
conversion from float32 to int64 was successful or not. The second output
returns 0 if the conversion fails, or something else if the conversion succeeds.
The second output can be ignored, which means that the operator can be used the
same as the original operator.
I implement the new operator on x64, arm64, and mips64. @v8-ppc-ports, can you
please take care of the ppc64 implementation of the second output?
